About Stinson Beach
Stinson Beach is one of the most popular swimming beaches in the Bay Area, a long sandy crescent in Marin County just north of San Francisco below the slopes of Mount Tamalpais. Backed by a small town and reached by a winding coast road, it draws summer crowds — though it lies within the 'Red Triangle,' a region known for white shark activity, and the water is cold. The Pacific here is cold and currents can be strong, so check the safety flag and rip-current risk above, be ready for cold water, and swim near a lifeguard.
